如果我沒有在我的孩子中找到我的針，但由於某種原因，我無法讓此工作，無論我嘗試了多少種不同的方式它，有人可能指向我在正確的方向嗎？這是在一個底層深度約爲4的多維數組中拋出的。下面是代碼和數組的一部分可能的樣子。在這種情況下，只有Array [3]應該保留，Array的[1-2]應該被移除。PHP如果未在數組中找到未設置的父項
array (

這是我嘗試使用的最後一個代碼沒有成功的樣本，如果你替換unset（$ k）;返回錯誤;它將返回其二級陣列針出現英寸
// array_search with recursive searching, optional partial matches and optional search by key
function array_find_r($needle, &$haystack, $partial_matches = false, $search_keys = false) {
if(!is_array($haystack)) return false;
foreach($haystack as $key=>&$value) {
$what = ($search_keys) ? $key : $value;
if($needle===$what) return $key;
else if($partial_matches && @strpos($what, $needle)!==false) return $key;
else if(is_array($value) && array_find_r($needle, $value, $partial_matches, $search_keys)!==false) return $key;
}
unset($k);
}
$tty = array();
foreach($datas as &$k) {
$tty[] = array_find_r('Jedi', &$k, true, false);
}
$tty=array_filter($tty); rsort($tty);
echo '<pre>'; var_export($datas); echo '</pre>';
